Kyle Jamieson hasn't been played till now but Williamson knows what kind of a nightmare he was with his steep back-of-length bounce generated from his 6 feet 9 inch frame.
If that's not enough, Wagner will pound it in with stuff aimed at rib-cage enticing the batters to go for the hook and pull shots or take it on the body.
In fact, Wagner versus Rishabh Pant could be one intriguing battle, knowing his love for the fallen hook shot.
Pant's self control and Wagner's relentless probe will make for a great contest.
Similarly, New Zealand's new star Conway would face a very different kind of challenge that Jasprit Bumrah will pose with awkward angles and the late swing that will be generated by Mohammed Shami.
Conway has, in fact, also prepared for Ashwin and Jadeja by sprinkling kitty litter on the practice pitches back to create rough which helps in getting the ball to turn and bounce.
This match could be one for the keeps unless pacers from either sides engineer an anti-climax.
